At first I was thinking about getting 5, because I have 5 slots for fans on my case, also I want good airflow, but these have a 55.2 decibel rating. So, I was wondering if anyone had these and would you recommend them because of the performance:sound ratio.

Or could anyone suggest a better setup besides 5 80mm fans.

Also I decided to get those 5 because I want my case as cool as I could get it. 5x84.1 cfm is 420.5 cfm, which is pretty **** good.

Those fans will spin at 5700 rpm. That is fast for a fan, and I highly recomend a fan bay controler of some sorts. This way you can turn them down and up when needed. I have a fan bay controler, and I dont keep the fans on max speed even when running my pc at max load for extended peroids of time.

In the future I suggest 120mm fans, these give you more air flow at lower speeds, which help with the noise issue. But those are fine fans for what you are looking for.

Most fan contolers have the ability of controling four fans, but that isnt a problem, just buy a three pin Y cable. You will then have to hook up two fans on one channel. So if you have two front intake fan, put both on the Y splitter, and you control them at once.

Where are the locations of the five available places for the fans? If they arent all in the same place it might be good to use all of them, but if you want to limit noise, you might not need to have all of them, and still have decent air flow.

Originally posted by chevytrucknut I've seen that fan before, and I reccomend not getting it. Just my 2 cents, but it is QUITE loud...go with what AND YOU ARE said, and see if you can get a 120mm

Well its hard to install 120mm fans in a case with 80mm fittings (there are adapters, but it will add cost, and there isnt always space). All I suggested is that with those fans (espicaly 5) you will need a fan controler to keep the noise down.
